Heavy Duty C Series Beam Pumping Unit for Oil Wells

Heavy Duty C Series Beam Pumping Unit for Oil Wells. Crank-balanced design The C Series uses crank balance to counterbalance the polished-rod and sucker-rod loads and improve mechanical efficiency. PI 11E design C Series pumping units are manufactured according to A P I Spec 11E Specification for Pumping Units, where the specific manufacturer/product is licensed and certified accordingly. Heavy-duty walking beam The walking beam is typically constructed using an H-section or comparable high-strength structural design, providing high rigidity and load-bearing capacity. Reliable gearbox Depending on the design, the reducer uses involute or double-arc herringbone gearing, providing smooth transmission, good sealing and high load capacity. Modular construction Modular and standardized components facilitate manufacturing, spare-parts management, installation and maintenance. Structural reliability Key structural components can be evaluated using finite-element analysis (FEA) during design to verify strength and structural performance. Easy maintenance The conventional mechanical arrangement provides relatively straightforward access to major components such as the gearbox, crank, pitman, brake and drive system.
